This is the deck I used to go from G1 to Masters this season. I used a different deck to get to rank 5.
It is an "All in" version of the Iron Forge deck, and plays very similar to Autotread Houndmaster aggro decks, but this one also makes 5/5 dragons along the way.
The ShiftstonedEternal Power Calculator is a deck-building tool that visualizes your odds of drawing enough Influence and Power based specifically on the cards found in your deck.
Not at all, unfortunately. Both Grenahen and Crafty would no longer be reasonable cards in a deck like this. I would likely cut Primal entirely now and go a different direction with a factionless deck in expedition.
